Recommendations for Image Acquisition for 3D Room Scanning

Proper image acquisition plays an extremely important role in 3D scanning of rooms, determining the completeness and correctness of the created model. Any mistakes made at this stage can cause a need to supplement the set of photographs or even to repeat the photo session, e.g. in case of changing the lighting conditions. This paper presents a set of recommendations minimizing the risk of making a mistake at the stage of acquiring photographs of interiors. These recommendations were based on numerous experiments carried out as part of the STERIO project which main goal is to develop a complete technology of faithful reconstruction of the real world interior sceneries in a virtual world of video games using stereophotogrammetry methods.
